That is a very sad situation beta, but don’t worry. The thing is perhaps you need to ask her about what she likes and enjoys in sex… what is she missing and what she wants in sex. The other thing is you may want to check how comfortable she is how relaxed and is she has any fears around having sex. Also ensure she has no infection or discomfort in and around her vagina, which could also be the problem. Get to know her body better, talk to her and find out what she is looking for. I hope this helps.
